no, the stock fuel rail and fpr are actually very well designed.
But it really depends on how much power you are making..

If you are in the 350 + range, then I would get a new FPR

 

I agree. Don't worry about it. Spend your money somewhere else.

 

cool so i should be ok running the aftermarket fuel pump with the stock fuel pressure regulator and stock fuel rail?

 

It will be fine to keep your stock fpr. But when you need to lower or raise your pressure you will not be able to with the stock fpr.

 

Your gonna want to dip into your car $$$ and pick yourself a fpr. Your gonna wanna bump it up , you will see better results but a loss in fuel economy , but oh well right. your stock fpr will be fine for now but your gonna want to adjust your pressure in the future.

 

Here's a recent thread on fuel pressure for 4th gens https://honda-tech.com/zerothread?id=685846&page=1

 

thanks, but yeah i dont plan on needing adjustments...im just gonna be running I/H/E with this motor and thats it...
